Genesis 39:6-9

So Potiphar placed all that he owned under Joseph’s oversight. And with Joseph in charge, Potiphar had nothing to worry about, except deciding on what to eat! Now Joseph was strikingly handsome, very good-looking, and well-built. It wasn’t long before his master’s wife noticed Joseph. She demanded: “Come make love to me.” “Never!” Joseph replied. “Don’t you realize that my master has nothing to worry about with me in charge, for he has put everything he has under my care? There is no one greater in his household than me, nor has he kept anything back from me except you, because you’re his wife. Why would I want to do such an immoral thing and sin against God?”
